Thank you for your custom bore 18” propeller. Finally could mount it and test it today. Awesome difference. A little more noisy than my old 16”, but could not hear it over 5 knots. And I finally have a boat I can manouver in the harbour.
I can also add in the harbour, I now know I have more stopping power, so I can manouver in higher and safer steering speed.
